Is Isopropyl Alcohol Better Than Degreaser?

How Does Isopropyl Alcohol Compare to Degreaser?

Isopropyl alcohol is excellent for removing the last traces of silicone and other contaminants from resin surfaces. It evaporates quickly, leaving no residue behind, making it a popular choice for final surface cleaning, prepping silicone moulds, and creating effects in resin art. However, it does not break down heavy grease or thick residue.

On the other hand, a dedicated degreaser—such as the Strong Technical Degreaser for Resin Projects—is formulated to lift bulk residues, including oils and hardened silicone, from a variety of surfaces. It’s particularly useful as a first step before switching to isopropyl alcohol for a spotless result.

Recommended Cleaning Process

• Step 1: Use a degreaser first to tackle the bulk of sticky or greasy residues. Its natural, solvent-free formula makes it suitable for common resin project surfaces like metal, ceramics, or silicone moulds.
• Step 2: After removing most of the residue, wipe the area with isopropyl alcohol. This removes fine traces and ensures the surface is clean and ready for casting or finishing.
• Precaution: Always follow safety instructions: isopropyl alcohol is highly flammable and should not be used near heat sources.

When This Matters Most

Getting a perfectly clean resin workspace is crucial before casting, sealing, or polishing. Using both a degreaser and isopropyl alcohol in sequence helps avoid surface defects, poor adhesion, or unexpected reactions that can result from lingering residues.
